This invention relates to an improved automatic 'apparatus for 'charging containers with liquids 'and the like; and its obgect, broadly speaking, is to provide an automatically operating device of simple .construction which allows of charging containers with liquids or similar fluids in predeterf mined amounts, which can be controlled. at will, the operation of the apparatus taking place in a continuous manner.

The invention has other objects also which will be clearly described in the course of this spec-ilicati'on and will be claimed hereinafter.

In order that the invention may be readi- -ly understood and carried into practice, a preferred embodiment of the same has been illustrated in the accompanyii'ig drawings, wherein Figure 1 is a plan view, ypartially sectional and with parts broken away or omitted, of

Y the complete apparatus. f D

Fig. 2 is a central longitudinal section on line 2-2, Fig. 1.

Figs. 3, 4 and 5 are cross-sections taken, respectively, on lines 3-3, 4 4, and 5-5 of Fig. 2; and p Fig. 6 is a cross-section taken substantially on the line 6-6 of Fig. 2. n

- According to the form of construction shown, the apparatus consists of a controller compartment 1, in the interior of which is mounted, in suitable bearings 2 and 8, a. controller in the form ofl a hollow cylindrical body 5 having rounded ends and adapted to tilt or oscillate on its axle 4. rlhis body or container 5 is provided oii its! upper side with a lid or cover 6 which closes an inlet for theadmission of a liquid or fluid, such as oil, for' instance, and a heavy ball7 is adapted to roll freely in the interior of. said body, the oil contained therein serving to damp its iinpacts against the ends of the same. Below the body 5 is securely supported a rail or track 8, along which runs a roller`9; the

' ends of the rail being curved upward and having their upper portions 8 bent slightly inward so that the roller will tend to stay within either of them, whereby the body 5 will be caused to occupy normally one or the other of its inclined positions, as shown in Fig. 3. The rail 8 is provided at opposite ends with stops 10 against which a pair of arms 1l. suspended from said roller and cai'- rying at their lower ends a roller 12 is adapted to abut;- said. roller 12 being are ranged to travel on ajointed bar 12', thetwo' members of which are provided with. stops 13 and pivoted at their outer ends 14 to the end walls of the compartment l, while their slotted inner ends have a lost-motion pivotal mounting on a pin 15 attached tothe top of a hollow float 16 which substantially fills the lower part of the interior of the compartment.' The float 16 rises or descends asthe liquid enters into orissues from thefloat chamber 16 (Fig. 3) beneath the same.

This chamber 16 is equipped with two gate valves 17 and `184 (Fig. 4) which alter;

nately open and close by the operation of4 a pair of arms 19 and 20 connected to links 21 and 22 which, in turn, are connected by means of links 23 and -24 `tothe ends of a walking beam 25, the axle of which constitutes an extension ofthe aXle 4 of the tilting body 5, so that the movements of said body and axle will betransmitted tofthe lsaid valves so as to alternately open and close- I the same. These valves 17 and.18 control, communication between the -iioat chamber orv compartment 16 and two compartments 26 and 27 which serve as discharge'reservoirs and whiclrare provided at their bottoms with outlet spouts 28 and 29 (Fig. 6). `-rlhe spouts are alternately, opened and closed by means of valves 30 and lprovided with deL pending `fingers 32 suitably guided in gratf` ings 33; and on the lower end ofeach spout is fitted a nut 34 constructed in such va wayV as to avoid the formation of whirls in the outflowing liquid. The stenis35 and36 of valves BO and 51l are provided with collars 37, to which are pivotedforks 38 and 39 se-k cured to horizontallyarranged, .longitudinal shafts 40 and 41l (Fig. 1) to which motion is imparted by thel previously-mentioned links 21 and 22 connected tothe gate. valve arms 19 and 20. By means of this arrange# the two partments 44 and45 (Fig. l) which are ar rangedat the ends thereof, by means of theV siphons 46and 47.; The siphdifisf`-terminatef in tubes 48 disposed in the regulating compartments 44 and 45, each tube being iitted at itsJ upper end with a gland 49; and within each tube slides another tube 49 (Fig. 2), the upper open end of which is connected to the lower face of a funnel or hopper 50 which extendssubstantially over the entire area of the regulating compartments and has an opening in register with the tube end.. Each funnel 50 has connected to it a vertical rod 51 carrying a vertical rack 52, that meshes with and is operated by a pin- Y ion 53 provided with a crank or other suitable device (not shown) for rotating it. The rack 52 is located immediately adj acent to and works in conjunction with an indieating scale 54. Y

The regulating compartments 44 and 45 being in communication with the discharg-v ing compartments v2.6 and 27 through the charging compartmentmay be controlled atwill.

Above the discharging compartments 26 and 27 is arranged the main charging reservoir 55, provided with'` an inlet-56 having a valve 57 which is operated through suitable linls 56 by a float 59 disposed within said reservoir or compartment. In the bottom oi' the reservoir are provided two ports 60 and Y'61 (Fig. 5) in Communication with the discharging compartments 26 and 27, respectively, and which open into pipes 62 and 63 that extend nearly to the bottom ot said compartments in order to avoid foaming, as will be readily understood. Said `ports 60 and 61 are closed by valves 64 and 65 guided in cages 66 and 67 and adapted to be operatedby a walking beam 66 pivoted at 69 Y and' provided with a lug` or projection 70 versa.

idlysecured to the main axle 4.

kin engagement with a fork 71 which is rig- The arrangement ofthe valves 64, is such that while the outlet valve 30 or 31 'of a discharging compartment is closed, its

inlet valve`64 011-65 will be open, and vice Similarly, when the inlet valve 1s open, thel gatev or regulating valve 17 or 16 leading to the float chamber 16 beneath the float'16 in compartment 1 will also be open. As the movements will take place in alternation with regard to each vside of the apparatus, the-operation of th-e machine may be considered as being entirely continuous.

The changes of position of the valves will be effected by the alternate tilting movements oi the body 5, due to the successive admissions of iiuid or liquid to the iloatV are mounted glass tubes 74 and 75, each con 4taining a slidable plunger 76 or 77 that is rigidly connected to a rod 76 or 77 provided at its lower end with a iioat 78 or 7 9 'suitably guided in the interior of each of saidl compartments.

The operation is substantially as fol# lows Starting with the inlet valve 57 of the main reservoir 55 open, liquid will iiow through inlet 56 and iill said reservoir until the level has risen far enough to cause iioat 59 to close the valve. Assuming that valve 64, which controls port 60 and pipe 62l leading into discharging compartment 26. is open, and that gate valve 17 controlling the entrance oit' the fluid into iioat chamber 16 is likewise open, then liquid from reservoir 55 will pass into said discharging compartment and also into said ioat chamber with the result that the compartment is filled and the float 16 is raised; it being understood, oi' course, that the corresponding discharge valve 30 is closed. At the same time, liquid also flows through siphon 46 and pipes 48 and 49 into the corresponding regulating compartment 44v and lills the same; theghop-A per 50 havingpreviously been adjusted by means of pinion 5 3 to the proper height for the particular quantity ot liquid to be discharged, which can readily be determined by the position of rack 52 relative to scale 54 (Fig. 2).

The iilling of float chamber 16 raises iioat 16, as just stated; and as the iioat rises, it pushes up the adjacent end of the hollow body 5, through the intermediary ofthe jointed bar 12, rollers 12 and 9, and arms 11. Said body 5 is thus tilted about its axis 4; and when said movement has progressed sutliciently far to enable ball 7 to travel to the other end of the hollow body, the tilting is completed, and the body will bc maintained injits'new position by the retention of the roller 9 in the curved'portion at the then lower end of rail 8. The'tilting movem-ent of the hollow body is transmitted through its axle 4 to the two walking-beams 25 and 68, so that valves 64 and 17 are now closed and the discharge valve 36 opened. Valves and 18 are also opened and-valve 31 is closed, in proper timed relation tothe first-named valves, .the two systems acting y'in alternation, as will be understood; Vbut since the operations are the same in'both cases, ya description of one cycle of'movements will suffice.

With the closing of valve 64 and opening of valve 30, the iow into compartment 26 is eut ofi' and discharge commences. The entire contents of said compartment will escape through outlet 28, and in addition all liquid in regulating compartment 44 above the level of hopper 50 therein will flou7 out through pipes 49 and 48 and siphon 46 into compartment 26 to be discharged With fthe liquid therefrom. The liquid in the float chamber 16 will escape through the opening controlled by valve 18 into compartment 27, the discharge valve 31 oi' which is closed at that time, as has been stated., so that float 16 falls and is ready for a fresh actuation.
